If you're really into the idea of doing a drastic change (meaning three or more shades lighter or darker than your natural color or switching it completely), visit the salon. At-home hair color should be about maintaining the shade that was designed for you by a colorist, not major changes, advises Dorram.
Cunningham first used chance in Sixteen Dances (1951) to determine the order of various segments into an established structure of dark, interlude, light, interlude, etc.; he also used charts and chance for the choreography and spacing of several dancers during one of the interludes.
I am not going to discredit you but I learned that shoes with the alluminum tap apearred after 1910 even though tap dance had been formed in the United States years before then. They were actually invented in Northern Korea by a man called Sinaf Choi in 1128, 149 years before tap dancing. This meant that lots of Chinese people didn't know what they were so they originally used them as ancient whacking device as punishment, much to Sinaf's disgust.
